Description
Verfahren zur Stabilisierung photographischer Emulsionen Gegenstand der Erfindung ist ein Verfahren zur Stabilisierung photographischer Halogensilberemulsionen, wobei man der Emulsion oder ihren Bestandteilen in einem beliebigen Zeitpunkt der Herstellung oder der fertig gegossenen Emulsionsschicht Salze von Sulfinsäuren oder Seleninsäuren einverleibt.Process for stabilizing photographic emulsions Subject the invention is a process for stabilizing photographic silver halide emulsions, wherein the emulsion or its components at any point in time Production or the finished cast emulsion layer salts of sulfinic acids or Selenic acids incorporated.
Gegenüber den bisher bekannten Stabilisatoren zeigen die vorliegenden Stabilisatoren den Vorteil, die photographischen Eigenschaf-. ten der Emulsion, beispielsweise Empfindlichkeit und Gradation, nicht zu beeinflussen.Compared to the previously known stabilizers, the present show Stabilizers have the advantage of having photographic properties. the emulsion, for example, sensitivity and gradation, not to be influenced.
Nach dem vorliegenden Verfahren können Alkali- oder andere lösliche Salze von aliphatischen oder aromatischen Sulfin- oder Seleninsäuren verwendet werden, beispielsweise Salze der Äthansulfmsäure, Äthandisulfinsäure, Benzolsulfinsäure, Chlorbenzolsulfinsäure, Toluol-p-sulfmsäure, Anisol-p-sulfinsäure, Acetani.hd-p-sulfinsäure, Benzol-m-disulfinsäune, Naphthalin-3-sulfinsäure, Chinolinsulfinsäure, Benzthiazolsulfinsäure, Benzselenazolsulfmsäure, Benztriazolsulfinsäure, Benzimidazolsulfinsäure, B@emzolseleninsäure. ' Die sulfinsaurm bzw. seleninsauren Salze können der Emulsion in einem beliebigen Zeitpunkt der Herstellung oder ,auch den Bestandteilen der Emulsion in Mengen von etwa 0,5 bis 5 g auf i kg nasser Emulsion zugesetzt werden; doch kommen gegebenenfalls auch größere oder kleinere Mengen, je nach der Emulsionsart oder den angewandten Sulfinsäuren, in Frage. Weiterhin können die Salze der fertig gegossenen Emulsionsschicht im Badeverfahren einverleibt werden. Nach diesem Verfahren können sowohl gewöhnliche als auch sensibilisierte oder hypersensibilisierte Halogensilberemulsionen oder andere Emulsionen mit speziellen Zusätzen stabilisiert werden. Beispiel i i kg einer gießfertigen Emulsion mit etwa 8 % Gelatine und etwa 5 % Halogensilber werde nach dem Aufschmelzen 49 benzolsulfnsaures Natrium zugesetzt. Die Emulsion wird hierauf in üblicher Weise vergossen. Beispiel a Eine Agfa-Isochrom-Platte wird i o Minuten in folgender Lösung gebadet: i 1 Wasser, 5 g Soda., krist., 5 ccm Ammoniak, konz., i o g benz.olsulfinsaures Natrium. Nach gutem Abspülen wird :die Platte in einem warmen Luftstrom getrocknet.According to the present process, alkali or other soluble Salts of aliphatic or aromatic sulfinic or selenic acids are used, For example, ethane sulfinic acid, ethane disulfinic acid, benzenesulfinic acid salts, Chlorobenzenesulfinic acid, toluene-p-sulfinic acid, anisole-p-sulfinic acid, Acetani.hd-p-sulfinic acid, Benzene-m-disulfinic acid, naphthalene-3-sulfinic acid, quinoline-sulfinic acid, benzothiazolesulfinic acid, Benzselenazole sulfinic acid, benzotriazole sulfinic acid, benzimidazole sulfinic acid, B @ emzolseleninic acid. 'The sulfinic acid or selenic acid salts can be used in any of the emulsion Time of manufacture or, even the components of the emulsion in amounts of about 0.5 to 5 g per 1 kg of wet emulsion are added; but come if necessary also larger or smaller amounts, depending on the type of emulsion or those used Sulfinic acids, in question. Furthermore, the salts of the finished emulsion layer can be used be incorporated in the bathing process. Following this procedure, both ordinary as well as sensitized or hypersensitized halogen silver emulsions or other emulsions can be stabilized with special additives. Example i i kg one A ready-to-pour emulsion with about 8% gelatin and about 5% halogen silver will follow 49 sodium benzenesulfate was added to the melting. The emulsion is on top shed in the usual way. Example a An Agfa isochrome plate is 10 minutes bathed in the following solution: i 1 water, 5 g soda., crystalline, 5 ccm ammonia, conc., i o g of sodium benzene-olsulfinate. After rinsing well, it becomes: the plate in one warm air stream dried.
